Question

If an object has a Mass of 11g and a volume fo 13mil, what is its density?

A.143g/ml
B.0.85g/ml
C.2g/ml D.24g/ml

Answer 1

`\boxed {\boxed {\sf B. \ d \approx 0.85 \ g/mL}}`

Step-by-step explanation:

Density is found by dividing the mass by the volume.

`d=(m)/(v)`

The mass of the object is 11 grams and the volume is 13 milliliters.

`m= 11 \ g \\v= 13 \ mL`

Substitute the values into the formula.

`d= (11 \ g)/(13 \ mL)`

Divide.

`d=0.846153846 \ g/mL`

Round to the nearest hundredth. The 6 in the thousandth place tells us to round the 4 to a 5.

`d \approx 0.85 \ g/mL`

The density is about 0.85 grams per milliliter.
